  • Patent number: 10349673
    Abstract: The present invention relates to a composition having two or three film-forming agents for applying to cigarette paper, wherein the molecular weight distributions of the film-forming agents are statistically significantly different from each other. The invention further relates to a cigarette paper on which the composition is applied to discrete regions, wherein the regions are characterized by a value for diffusivity, and to a cigarette comprising the cigarette paper, characterized by values for auto-selection. The present invention further relates to a method for producing the cigarette paper and the cigarette.

  • Patent number: 10258078
    Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition is applied as multiple layers to the paper wrapper. After each application step, the wrapper is dried. Applying the film-forming composition to the paper wrapper in multiple layers minimizes distortion and other adverse affects that may occur to the wrapper.

  • Patent number: 9038644
    Abstract: Method of applying phase transition substance to impart reduced ignition propensity to a smoking article comprising a tobacco column and a wrapper surrounding the tobacco column and having a porous structure with a base permeability. The method comprising forming a pattern of phase transition material on the wrapper such that, when subjected to the heat of the tobacco column burning firecone, the phase transition material at least partially fills the wrapper porous structure in the vicinity of the burning firecone to form an area on the wrapper having reduced permeability lower than that of the wrapper base permeability. The reduced permeability of the wrapper in the vicinity of the burning firecone imparts reduced ignition propensity such that there is insufficient air flow to sustain combustion of the firecone or insufficient air flow to sustain an intensity of the burning firecone necessary to ignite the substrate.

    Abstract: The present invention describes a single-layer printing method of a wrapper for smoking articles, so as to obtain a wrapper for smoking articles with low propensity to ignition using the flexographic technique, characterized in that (1) the printing is carried out by means of a central drum flexographic printing machine using a single printing unit, (2) said unit has an anilox with a capacity of between 10 and 40 cm3/m2 and a printing cylinder equipped with a printing form selected from a stencil plate plus an adhesive, and a sleeve, and (3) in that an ink is used that comprises at least one film-forming substance and a mineral filler. The present invention also relates to the wrapper that can be obtained by this method and to the smoking article that includes said wrapper.

  • Patent number: 8869805
    Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. Smoking articles include a paper wrapper that is treated with a film-forming composition. The film-forming composition forms treated discrete areas on the wrapper. The treated discrete areas reduce ignition proclivity properties of the smoking article made with the wrapper. The film-forming composition contained a film-forming material blended with a burn promoting agent in the absence of a burn retardant. In one embodiment, for instance, the film-forming composition consists essentially of a film-forming material and a burn promoting agent. Various advantages and benefits are realized by blending a film-forming material with burn promoting agent without also incorporating a burn retardant into the composition.

  • Patent number: 8863757
    Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition contains a film-forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.

  • Patent number: 8863750
    Abstract: A cigarillo includes a tobacco rod including a tobacco cut filler circumscribed by an inner binder, a filter adjacent to the tobacco rod, a band of tipping paper circumscribing the filter, and an outer wrapper of natural tobacco circumscribing the tobacco rod and a rod end portion of the band of tipping paper such that a mouth end portion of the band of tipping paper is visible. A method of making the cigarillo includes convoluting an inner binder around a tobacco cut filler to form a tobacco rod, axially aligning and abutting a filter with the tobacco rod, convoluting a band of tipping paper around the filter, and convoluting an outer wrapper of natural tobacco around the tobacco rod and a rod end portion of the band of tipping paper such that a mouth end portion of the tipping paper is visible.

  • Patent number: 8852350
    Abstract: A smoking article, and a method and apparatus for producing a smoking article, in which a web material containing an adsorbent material such as activated carbon and a stabilized flavorant such as menthol is positioned adjacent an interior surface of a cigarette wrapper to deliver flavor to a smoker with minimal/insignificant migration of flavor to other parts of the smoking article or packaging. The web material may be a section that extends over only a portion of the smoking article to deliver flavor to a smoker at a specific point during smoking and if positioned at the mouth end of a smoking article will be able to deliver a flavor sensation in the final puff(s).

  • Patent number: 8844540
    Abstract: Wrapper for cigarette manufacture includes transversely extending band regions applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate. Any suitable printing technique can be used to apply the aqueous solution to the banded regions. The pattern of banded regions may be bands, stripes, two-dimensional arrays, undulated regions, and the like along and/or around the tobacco rod. The pattern can be applied in one or more layers. The pattern may be configured so that when a smoking article is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film-forming compound located only on sides of the smoking article not in contact with the substrate.
